In Chapter 2, once you’ve collected the Rose Light bottle from the Rabbit Puzzle, and the Skull Light bottle from the Skull Puzzle, and the Pumpkin Light bottle from the Pumpkin Puzzle, and completed the Scarecrow Puzzle, you’ll be ready to enter the windmill and collect ingredient number two – Melitta’s Nectar.

In order to get the gate lock open, use the symbols from the Scarecrow Puzzle
Use the Beast Eyeball from the Painting Canvas Puzzle to run the maze, being sure to interact with each of the 3 circle spots. Each circle spot unlocks one of the lower openings where the bottles go, so it’s important to run the Beast Eye through all of them.
Once you’re through the maze, drag the ball down to the lower area. Drag it left and right along the horizontal line to open the little doors where the bottles go. Place all 3 bottles in their respective slots and the last door will open, revealing the next ingredient for Grandma – Melitta’s Nectar.
